The active compound is generally present in amounts ranging from about 0.1 to 5%, preferably about 1.5 to 2 weight percent of the total composition.

METHOD OF PREPARATION

In a general manner, active compounds of the present invention can be prepared by the reaction of a thiol, with an organic halide or with an ester of methane sulfonic acid or p-toluene sulfonic acid (Method I), or with a compound having a reactive double bond (Method II), or with an oxirane (Method IV), or with an alcohol (Method III) or with ethylene imine and its acylation and sulfonylation derivatives (Method IV).

METHOD I

The most commonly employed procedure is the substitution reaction of essentially an equimolar ratio of a thiol with an organic halide or a methane sulfonate or a p-toluene sulfonate. The thiol can be aminated or not. The reaction is carried out under conditions generally or conventionally employed for nucleophilic substitutions including, for instance, a temperature ranging from 10° to 100° C., atmospheric pressure, and employing a solvent such as water, ammonia, alcohol or dimethyl formamide in the presence of a base such as an alkali or alkaline earth hydroxide, or carbonate, an alcoholate, an alkali or alkaline earth amide or even a tertiary aliphatic amine such as triethylamine according to the following general reaction:

    R--X+R'--SH→R--S--R'+XH

    (X=halogen or --OSO.sub.2 CH.sub.3 or --OSO.sub.2 C.sub.6 H.sub.5)

or

    R'--X+R--SH→R'--S--R+XH

The thiol R--SH or R'--SH can be prepared in situ by basic hydrolysis of an isothiouronium salt according to the following general reaction: ##STR13##

METHOD I (ALTERNATIVE)

When R is an aryl radical (X=O), the halide employed is an aryldiazonium halide (Vigneaud et al, J. Biol. Chem., 1941, 138, 369 and Clarke and Inouye, J. Biol. Chem. 1931, 94.541) and the reaction follows the general equation:

    ArN.sub.2 Cl+R'--SH→Ar--S--R'+N.sub.2 +HCl

METHOD II

The addition reaction of essentially an equimolar ratio of a thiol with a compound having a reactive double bond is well known and can be carried out, in accordance with known procedures, without a catalyst or in the presence of a peroxide such as ascaridole, benzoyl peroxide, aza bis-isobutyronitrile, or in the presence of a base such as those employed in Method I, or even a quaternary ammonium hydroxide or a secondary amine such as piperidine. Representative reaction temperatures include 10° to 100° C. and at atmospheric pressure.

The reaction is most generally effected in a medium such as alcohol, for instance, lower alkanol, water, dioxane; alone or in admixture, with a basic catalyst, so as to obtain a small quantity of thiolate to initiate the reaction.

The compound utilized having a reactive double bond does not have an amine function. It can, however, contain an amide or sulfonamide function.

The radical R can originate from either a compound having a reactive double bond (scheme 1) or from a thiol (scheme 2) when R₃ and A are other than hydrogen. ##STR14##

METHOD III

The compounds of the present invention, in which the sulfur atom is linked to a disubstituted or trisubstituted carbon atom, or to a benzyl or allyl radical, can conveniently be prepared at a temperature ranging from about 50° to 150° C. and at atmospheric pressure by reaction of essentially equimolar amounts of a corresponding tertiary or secondary, benzyl or allyl alcohol, with a thiol, in the presence of a strong acid such as gaseous hydrochloric acid, p-toluene sulfonic acid, or a Lewis acid such as the etherate of boron trifluoride, in accordance with the following general reaction: ##STR15## R"; and R"" only represents hydrogen when R" represents aryl or vinyl.

METHOD IV

Another particularly useful method for preparing compounds of the present invention consists of reacting essentially equimolar amounts of a thiol with an ethylene imine or an acylation of N-sulfonylation derivative thereof at a temperature ranging from about -30° to 80° C. at ambient or atmospheric pressures according to the following equations which provide an easy method of producing the following compounds: ##STR16##

The reaction is made very easily, in a variety of solvents, chosen as a function of the solubility of the starting materials. Representative solvents include alcohols of low molecular weight and chloroform.

METHOD IV (ALTERNATE)

The β-hydroxythioethers can be prepared by an analogous procedure, by replacing the azinidine by an oxiran, and by effecting the reaction in a polar medium with a basic catalyst, as in Method I according to the following scheme: ##STR17##

In addition to the above methods, the esters and the amides of the present invention can be prepared starting with other compounds.

Thus, esters can be obtained starting with the corresponding acid (R₇ =OH), by reacting an appropriate alcohol therewith to give the desired ester, either at an elevated temperature in the presence of a mineral or sulfonic acid, or at a low temperature in the presence of thionyl chloride (Method V).

Amides included in the meaning of R₃ can be prepared simply by the reaction of ammonia, hydrazine, hydroxylamine or an appropriate amine on the ester noted above, at a temperature generally lower than 30° C. (Method IV).

The amides included in A can be conveniently prepared by the action of a halide or anhydride of a carboxylic acid to produce a carboxamide or by the action of a sulfonyl halide to produce a sulfonamide when the amide is formamide, the amide is prepared by action of formic acid. The reaction conditions most generally utilized are those of Schotten-Baumann, i.e., in water, in the presence of an alkaline hydroxide, or their rearrangement in an organic medium (aromatic hydrocarbon, generally a chlorinated solvent) in the presence of a base such as pyridine or a tertiary amine, for example, trialkylamine (Method VII).

When it is desired to prepare acylated compounds having an alcohol function, they can be obtained by the action of an amine on a lactone, the reaction being catalyzed by an alkaline alcoholate.

In the case of substituted acetamides, acetylation of the amine can often advantageously be effected by means of acetic anhydride in an acetic acid medium in the presence of concentrated sulfuric acid.

It will be noted, however, that the majority of the amides included in the meaning of A are in addition easily produced by one or more of Methods I-IV.

Finally, compounds of the type where A equals --CONH₂ are prepared by the action, in an aqueous or aqueous alcoholic medium, of an alkaline cyanate on a compound of the type A=H, in the presence of an equivalent amount of mineral acid, preferably, hydrochloric acid (Method VIII), the starting compound being obtained according to Methods I-IV.

The preparation of the salts of the active compounds is generally carried out by first dissolving the acid in an appropriated solvent and then pouring to this solution either a solution of the active compound in the same solvent or the active compound alone. The solvent must not be a solvent of the salt.

To prepare hydrochlorides, it is more convenient to dissolve the active compound in an appropriated solvent and then to bubble in the solution a slight stream of hydrogen chloride.

The following reducing composition is prepared:

    ______________________________________                                         Ammonium thioglycolate     9.5    g                                            Fatty alcohol polyethoxy-ester                                                 (Cetyl alcohol 30% Stearyl alcohol 70%)                                        sold under the trade name "Sipol Wax A.O."                                                                0.8    g                                            Ammonia, q.s.p. solution   0.7    N                                            5-amino 3-thia hexanedioic acid                                                                           1.2    g                                            Water, q.s.p.              100    g                                            ______________________________________                                    

After shampooing and drying, the hair is wound on curlers and is impregnated with the above composition. The composition is allowed to act for 15 to 30 minutes. Thereafter, the hair is thoroughly rinsed and there is then applied to the hair a neutralizing composition comprising a 6-volume hydrogen peroxide solution. The curlers are removed and the hair is rinsed and dried. The hair thus permanently waved in accordance with this invention exhibited a nonoily appearance for a significantly longer time than did the hair when permanently waved using essentially the same cosmetic composition but without the 5-amino 3-thia hexanedioic acid.

EXAMPLE 94

The following reducing composition is prepared:

    ______________________________________                                         Thioglycolic acid         8     g                                              Mono-ethanolamine        5.3    g                                              Ammonium bicarbonate     7.7    g                                              Trimethyl-cetyl ammonium bromide                                                                        0.2    g                                              Urea                     5.0    g                                              3-(4-carboxy butylthio) alanine                                                                         0.5    g                                              Water, q.s.p.            100    g                                              ______________________________________                                    

Proceeding as in Example 93, the above composition is applied to pre-shampooed and dried oily hair in the first stage of the permanent waving operation. Thereafter the hair is neutralized essentially as described above and a permanent wave of good quality is obtained. As before, the hair permanently waved in accordance with this invention exhibited a non-oily appearance for a significantly longer period of time than did the hair when permanently waved using essentially the same cosmetic composition but without the 3-(4-carboxy butylthio) alanine.

EXAMPLE 95

The first stage, i.e., the reducing stage, of a permanent wave operation is achieved essentially as set forth in Example 93 but with a cosmetic composition containing:

    ______________________________________                                         Ammonium thioglycolate     9.5 g                                               Fatty alcohol polyethoxy-ester (cetyl alcohol                                  30% - stearyl alcohol 70%) sold under the                                      trade name of "Sipol Wax AO"                                                                              0.8 g                                               Ammonia solution, q.s.p.   0.7 N                                               Water, q.s.p.              100 g                                               ______________________________________                                    

Thereafter the hair, while still rolled on curlers, is neutralized by applying to the same the following neutralizing composition:

    ______________________________________                                         Sodium bromate           18    g                                               3-(carboxy methylthio) alanine                                                                         0.5    g                                               Water, q.s.p.           100    g                                               ______________________________________                                    

After rinsing, the curlers are removed and the hair is then dried. A good permanent wave is obtained and the hair remained non-oily in appearance for a significantly longer time than did the hair when permanently waved using a cosmetic composition essentially as described above but without any 3-(carboxy methylthio) alanine.

EXAMPLE 96

To give a permanent to hair with an oily appearance, a one stage permanent wave solution having the following composition is prepared:

    ______________________________________                                         Glycol thioglycolate     6     g                                               Glycol dithiodiglycolate                                                                               18     g                                               5-p-toluene sulfonamido 3-thia                                                 hexanedioic acid        1      g                                               Ammonia q.s.p.          pH     9.5                                             Water, q.s.p.           100    cc                                              ______________________________________                                    

After the hair has been shampooed and dried, each lock is impregnated with said solution and is then wound on curlers with a medium diameter. When the rolling has been completed, all the locks are saturated with the same solution and the head is covered with a cap. The solution is permitted to remain on the hair for a period of about 20-25 minutes. The hair is then carefully and abundantly rinsed in lukewarm water. After the curlers are removed the hair is rinsed again. The permanent wave achieved is very pronounced and supple and the hair remained non-oily in appearance for a significantly longer time than did the hair when permanently waved using essentially the same cosmetic composition but without the 5-p-toluene sulfonamido 3-thia hexanedioic acid.

EXAMPLE 97

To permanently wave hair presenting an oily appearance, a two-package reducing composition is employed.

The first package contains:

    ______________________________________                                         Ammonium thioglycolate   9.5    g                                              Monoethanolamine, q.s.p. solution                                                                       0.65   N                                              Ammonium lauryl sulfate  0.5    g                                              Water, q.s.p.            100    g                                              ______________________________________                                    

The second package contains:

    ______________________________________                                         S--(β-aminopropyl) mercaptoacetic acid                                    in powder form.          1 g                                                   ______________________________________                                    

Immediately prior to initiating the first stage of the permanent waving operation, i.e., the reducing stage, the powdered S-(β-aminopropyl) mercapto acetic acid is dissolved in the aqueous solution constituting the first package.

The hair, wound on the curlers, is then impregnated with the resulting solution and the method outlined in Example 93 is repeated. A permanent wave is obtained which exhibits good holding characteristics and the hair remained non-oily in appearance for a significantly longer time than did the hair when permanently waved using essentially the same reducing composition but without the S-(β-aminopropyl) mercapto acetic acid.

EXAMPLE 98

The first stage, i.e., the reducing stage, of a permanent waving operation is performed with a reducing composition containing:

    ______________________________________                                         Ammonium thioglycolate    9.5 g                                                Fatty alcohol polyethoxy-ester (Cetyl                                          alcohol 30% - stearyl alcohol 70%)                                             sold under the trade name of "Sipol                                            Wax AO"                   0.8 g                                                Ammonia solution, q.s.p.  0.7 N                                                Water, q.s.p.             100 g                                                ______________________________________                                    

A two-package neutralizing composition is then employed, the first package containing:

    ______________________________________                                         Hydrogen peroxide, q.s.p.                                                                             6.6    volumes                                          Citric acid            0.1    g                                                Water, q.s.p.          100    g                                                and the second package containing:                                             3-(2-pyridyl methylthio) alanine in                                            powder form            5      g                                                ______________________________________                                    

Immediately prior to initiating the second stage of the permanent waving operation, i.e., the neutralizing stage, the powdered 3-(2-pyridyl methylthio) alanine is dissolved in the hydrogen peroxide solution and the hair previously treated with the above reducing agent, being soft and pliable and still wound on curlers, is treated with the resulting neutralizing solution for a time sufficient to reform the disulphide bonds in the keratin of the hair.

After the hair has been rinsed, unwound from the curlers, and dried, a permanent wave is obtained which exhibits good holding characteristics. Equally important, however, is that the hair remained non-oily in appearance for a significantly longer time than did the hair when permanently waved using essentially the same neutralizing composition but without the 3-(2-pyridyl methylthio) alanine.

EXAMPLE 99

The first stage, i.e., the reducing stage, to obtain a permanent wave in oily hair is performed, after shampooing the hair, with a two-package reducing composition wherein the first package contains:

    ______________________________________                                         Ammonium thioglycolate   9.5    g                                              Monoethanolamine q.s.p. solution                                                                        0.65   N                                              Ammonium lauryl sulfate  0.5    g                                              Water, q.s.p.            100    cc                                             and the second package contains:                                               2-furfuryl thioethyl ammonium malate                                                                    1      g                                              ______________________________________                                    

The contents of the second package are dissolved in the aqueous reducing agent of the first package. Thereafter the method outlined in Example 97 is repeated. An equally good permanent wave is obtained with comparable non-oily appearance characteristics.

EXAMPLE 100

By proceeding as indicated in Example 98, the second stage of a permanent wave operation is performed for oily hair with a two-package neutralizing composition. The first package contains:

    ______________________________________                                         Hydrogen peroxide, q.s.p.                                                                              6.6    volumes                                         Citric Acid             0.1    g                                               Water, q.s.p.           100    cc                                              and the second package contains:                                               3-benzylthio propyl ammonium glycolate                                                                 5      g                                               ______________________________________                                    

The contents of the packages are mixed just before the second stage operation is initiated. The resulting permanently waved hair exhibits non-oily appearance characteristics comparable to that achieved when the method of Example 98 was followed.

The methods outlined in Examples 93-100 are repeated using in certain instances, other compounds enumerated above, in the reducing composition, and in other instances in the neutralizing composition and in amounts essentially equivalent to those specified in Examples 93-100.

EXAMPLE 101

The following reducing composition is prepared:

    ______________________________________                                         Ammonium thioglycolate    9.5    g                                             Fatty alcohol polyethoxy-ester (cetyl                                          alcohol 30% - stearyl alcohol 70%)                                             sold under the trade name "Sipol Wax AO"                                                                 0.8    g                                             Ammonia q.s.p. solution   0.7    N                                             2-Acetamido 3-phenylthio alanine                                                                         2      g                                             Water, q.s.p.             100    g                                             ______________________________________                                    

After shampooing and drying, the hair is wound on curlers and is impregnated with the above composition. The composition is allowed to act for 15 to 30 minutes. Thereafter, the hair is thoroughly rinsed and there is then applied to the hair a neutralizing composition comprising a 6-volume hydrogen peroxide solution. The curlers are removed and the hair is rinsed and dried. The hair thus permanently waved in accordance with this invention exhibited a non-oily appearance for a significantly longer time than did the hair when permanently waved using essentially the same cosmetic composition but without the above active compound.

5. MISCELLANEOUS CARRIERS EXAMPLE 102

A composition for treating the scalp to reduce excessive secretion of sebum is made by homogenizing 1.5% by weight of 3-tritylthio alanine and 0.1% of perfume in olive oil.

EXAMPLE 106

A dermatological cake is prepared which is identical to the one described in Example 105 except that the 3-carboxymethylthio alanine is replaced by di-(2-benzylthio ethylammonium) fumarate.

EXAMPLE 107

A dermatological cake is prepared which is identical to the one described in Example 105 except that the 3-carboxymethylthio alanine is replaced by 3-benzylthio propylammonium p-aminobenzoate.

EXAMPLE 108

A dermatological cake is prepared which is identical to the one described in Example 105 except that the 3-carboxymethylthio alanine is replaced by 2-benzylthio ethylammonium pantothenate.

In the above examples, the active compound is present generally in amounts ranging from about 0.1-5 weight percent of the total composition. When the carrier is an aqueous alcohol solution, the alcohol employed generally is a lower alkanol having about 1-4 carbon atoms, the alcohol being present in amounts of about 20 to 70 weight percent of the solution. These same lower alkanols of course can be used without water when desired.

In the examples where a detergent is employed in the composition, detergents such as cationic detergents, for instance lauryldimethylbenzyl-ammonium chloride, stearyldimethylbenzyl-ammonium chloride, anionic detergents such as sodium lauryl sulphate and nonionic detergents such as sorbitan monolaurate can be used.

A typical example of a shampoo contains 7% by weight stearyldimethylbenzyl-ammonium chloride, 2% 2-propionamido 4-thia heptanedioic acid, 93% water plus a perfume and coloring agent, if desired. The shampoo is then applied to the scalp in the manner one would apply any other shampoo. That is to say the hair is rinsed with water, the shampoo is applied and rubbed into the hair and scalp, then the hair is rinsed with water to remove the shampoo. Preferably this is followed by a second shampoo washing.

Other detergents usefully employed include: anionic detergents such as: alkyl sulfates, alkyl ether sulfates, alkyl polyether sulfates, alkyl sulfonates, in which the alkyl groups have 8 to 18 carbon atoms, sulfated monoglycerides, sulfonated monoglycerides, sulfated alkanolamides, sulfonated alkanolamides, soaps of fatty acids, monosulfosuccinates of fatty alcohols, the products of the condensation of fatty acids with methyl-taurine, the products of the condensation of fatty acids with sarcosine, the products of the condensation of fatty acids with a protein hydrolysate; cationic detergents such as long chain quaternary ammonium esters of fatty acids and of amine alcohols, polyether amines, non-ionic detergents such as: the esters of polyols and sugars, the products of the condensation of ethylene oxide with fatty acids, fatty alcohols, long chain alkyl phenyls, long chain mercaptans, and long chain amides, the polyethers of polyhydroxylated fatty alcohols: or amphoteric detergents such as asparagine derivatives, the products of the condensation of monochloroacetic acid and imadazolines, and alkyl aminopropionates.

Among the non-ionic detergents which can be utilized are:

lauryl alcohol oxyethylenated with 12 moles of ethylene oxide;

C₁₂ thiols oxyethylenated with 12 moles of ethylene oxide.

Among the cationic detergents which can be utilized are:

lauryl benzyl dimethyl ammonium bromide or chloride;

cetyl trimethyl ammonium bromide; myristil benzyl dimethyl ammonium bromide or chloride;

cetyl benzyl dimethyl ammonium bromide or chloride.

Among the amphoteric detergents which can be utilized are:

lauryl aminopropionate of a radical derived from copra fatty acids;

alkyl dimethyl betaine;

compounds of formula: ##STR42## in which R is a radical derived from copra fatty acids having 6-18 carbon atoms and an alkyl derived from tallow.

The shampoos according to the invention generally contain from 0.5 to 5%, and preferably 1 to 3% by weight of the said active compound. They also contain, for example, from 4 to 15%, and preferably from 5 to 7% by weight of the detergent compound in an aqueous medium.

The shampoos according to the invention may also contain other conventional cosmetic ingredients, such as perfumes and hair dyes. They can also contain thickening agents such as the alkanolamides of fatty acids, cellulose derivatives (carboxymethylcellulose, and hydroxymethylcellulose, for example), esters of long chain polyols, and natural gums so as to take the form of a cream or gel.

The shampoos according to the invention may also take the form of a powder adapted to be applied to moistened hair, or to be dissolved in a certain volume of water before being used to wash the hair.

When the novel compositions of this invention include a cosmetic resin in combination with the active compound to provide a hair setting lotion or lacquer, useable cosmetic resins employed include, for instance, polyvinylpyrrolidone (M.W. 40,000) and generally between 10,000-70,000; polyvinylpyrrolidone/vinyl acetate copolymer 70%:30% to 30%:70% (K ethanol 1% 25-50); copolymer of vinyl acetate and an unsaturated carboxylic acid such as crotonic acid (M.W. 20,000); copolymer resulting from the polymerization of vinyl acetate (75-85%), crotonic acid 5-15% and an acrylic or methacrylic ester (5-15%), copolymer resulting from the copolymerization of vinyl acetate (75-85%), crotonic acid (5-15%) and vinyl alkyl ether (5-15%); copolymer resulting from the copolymerization of vinyl acetate (63-88%), crotonic acid (5-15%) and (a) a vinyl ester of a long carbon-chain acid having 10 to 22 carbon atoms or (b) an allyl or methallyl ester of a long carbon-chain acid having 10 to 22 carbon atoms (5-25%); copolymers resulting from the copolymerization of an ester derived from an unsaturated alcohol having 2 to 12 carbon atoms and a short chain carboxylic acid having 2 to 5 carbon atoms (65-80%) and a short carbon-chain unsaturated acid having 4 to 20 carbon atoms (7-12%) and at least one ester derived from a short chain saturated alcohol having 8 to 18 carbon atoms and an unsaturated acid having 4 to 20 carbon atoms (10-20%). The resin concentration generally ranges between about 1-20% by weight of the composition.

In a particular mode of operation, the cosmetic resins contained in the compositions according to the invention may present lateral or branch chains, at the end of which a thiol function is located.

The cosmetic resins contained in the compositions according to the invention may also consist of colored polymers, i.e., polymers containing in their macromolecular chain coloring nuclei which give a particular coloration or shade to the hair.

As indicated above, the novel compositions of this invention are employed as oxidizing or reducing agents in processes for permanently waving hair.

In one embodiment, the hair is permanently waved by applying to the hair wound on curlers during the first stage, i.e., during the reducing stage, a cosmetic composition comprising a mixture of a reducing agent and the active compound of this invention, defined above, permitting the composition to remain on the hair for a time sufficient to alter the disulphide bonds of the keratin of the hair, generally about 10 to 40 minutes, thoroughly rinsing the hair to remove residual reducing agent and applying in the second stage, i.e., during the neutralization stage, an oxidizing or neutralizing agent to reform the disulphide bonds of the keratin of the hair.

In another embodiment, the hair is permanently waved by applying to the hair wound on curlers during the first stage, i.e., during the reducing stage, a reducing agent, permitting the composition to remain on the hair for a time sufficient to alter the disulphide bonds of the keratin of the hair, generally about 10 to 40 minutes, thoroughly rinsing the hair to remove residual reducing agent and applying in the second stage, i.e., during the neutralization stage, a cosmetic composition comprising a mixture of an oxidizing or neutralizing agent and the active compound of this invention whereby the disulphide bonds of the keratin of the hair are reformed.

In yet another embodiment the hair is permanently waved by impregnating the hair wound on curlers with a cosmetic composition comprising a mixture of a thiol reducing agent for altering the disulphide bonds of the keratin of the hair, an organic disulphide and the active compound as hereinbefore defined, the molar ratio of said organic disulphide to said thiol being greater than 1, and as high as about 20, permitting the composition to remain on the hair for a time sufficient to induce a permanent wave therein, generally about 10 to 40 minutes, and unwinding the hair from the curlers. Conventional separate neutralization operations are not required in the practice of this embodiment of the invention.

The aforementioned active compounds used in these embodiments are admixed with a conventional reducing agent and are present in the resulting mixture in amounts between 0.1%-5% by weight of the total and preferably between 1 and 3 weight percent. The pH of this cosmetic composition is preferably between 3 and 9.5. Conventional reducing agents employed are advantageously those organic thiols which are generally used to perform the first stage of a permanent waving operation. Representative thiols include thioglycolic acid, ammonium thioglycolate, thioglycerol, thiolactic acid, thioglycolic amide or hydrazide or the like.

Conveniently, and also in accordance with the present invention, the reducing composition is a two-package composition, the first package containing a thiol reducing agent as described above and the second package containing said active compound in amounts such that when the contents of two packages are mixed together, preferably just before initiation of the reducing operation, the resulting reducing composition contains said active compound in amounts of about 0.1-5 weight percent of the total mixture.

Alternatively, the active compound is admixed with a conventional neutralizing or oxidizing agent and is present in the resulting mixture in amounts between 0.1 and 5 weight percent, and preferably between about 1 and 3 weight percent of the total. Conventional neutralizing agents employed include, for instance, hydrogen peroxide, sodium or potassium bromate, sodium perborate or percarbonate and the like.

Conveniently also, the neutralizing composition is a two-package composition, the first package containing the neutralizing agent as described above and the second package containing the acitve compound in amounts such that when the contents of the two packages are mixed together, preferably just before initiation of the neutralizing operation, the resulting neutralizing composition contains the active compound in amounts of about 0.1-5 weight percent of the total mixture.

As a further alternative, the active compound is admixed with a single stage permanent hair waving agent, and is present in the resulting mixture in amounts between 0.1-5 weight percent, and preferably, between about 1 and 3 weight percent of the total. Conventional single stage permanent hair waving agents can be employed and include a mixture of an organic disulfide and a thiol, the mol ratio of the disulfide to the thiol being greater than 1.

Suitable thiols include thioglycolic acid, glycol thioglycolate, glycerol thioglycolate, β-mercaptoethanol, N-carboxymethyl-mercaptoacetamide, glycol thiolacetate and the like.

As the organic disulphides there can be used the disulphides of the thiols set forth in the preceding paragraph. For instance, glycol dithiodiglycolate, glycerol dithiodiglycolate, glycol dithiodilactate, dithiodiethanol and N-carboxymethyldithioacetamide can be employed. Additional ingredients can include ammonia, water, urea and lower alkanols in conventionally employed amounts and the pH of the single stage permanent hair waving agent ranges between about 8-10, preferably about 8.5-9.5. Typical formulations of such single stage permanent hair waving agents are disclosed in French Pat. Nos. 1,443,888 and 1,455,788.

Again, conveniently, the single stage permanent hair waving composition is a two-package composition, the first package containing the single stage permanent hair waving agent and the second package containing the active compound of this invention as defined above, in amounts such that when the contents of the two packages are mixed together, preferably just before use, the resulting permanent hair waving composition contains the active compound in amounts of about 0.1-5 weight percent of the total mixture.
